3D Mouse support "NDOF" Blender is now built with support for 3D Connexion devices, for more natural control during view navigation and fly mode.

Custom Keymaps User edited keymaps now no longer override the builtin keymaps entirely, but rather save only the difference and reapply those changes. This means they can stay better in sync when the builtin keymaps change.

Ivy Generator (Addon) This tools adds the ability to "grow" curves over an existing mesh with the option of adding leaves and adjusting many parameters for the final result.

Grease Scatter (Addon) Grease scatter was used for sintel to place objects around the ally, using grease pencil lines as a guide as to where to scatter objects.
